Bothan Sherry Expression is a single malt whisky presented with a sherry-led style. For a new drinker, that usually suggests a richer, fuller profile than lighter house styles, often with more emphasis on dried fruit and oak.
Single malt means it is made from malted barley at one distillery. A sherry expression is typically aimed at drinkers who enjoy rounder, sweeter whisky flavours rather than a very light or sharply smoky profile.
